many years back i had a model A street rod up on 4 jack stands. As i was standing alongside it (small garage) it began to fall. I was able to hold it bracing myself between the car and workbench. Fortunatle the wife stepped out and got the floor jack under it. I had some deep offset 12" steel rims left over from another project. She said, put the rims under the tires on one end of the car, get rid of 2 or the JS and doing so will stabilize the car as the two tires will act like they are on the ground as they are trapped in the rim. HMM. Great idea and used it for years until I got the lift. Back then you could pick the rims up dirt cheap at swap meets as most people don't want a 12" + wide rim.
